553,405. Goggles. OLIVER, G. L. J. Sept. 9, 1941, No. 14193/40. [Class 97 (i)] The eye-piece components of goggles to be worn by pupils training during daylight for night flying, have small clear sections near the nose to permit viewing of the instrument panel, and screens entirely cutting out the remainder of the field of view or restricting the light brightness. The clear sections may be at the lower part of each component, and may be coloured to a lesser extent than the screens ; screening extensions may be formed at the top and sides of the goggles.
